The best time to visit Solok, West Sumatra, is during the dry season, which typically runs from May to September.
During these months, you'll experience less rainfall and more sunshine, making it ideal for exploring the region's natural beauty, such as Lake Singkarak and the surrounding tea plantations. The drier weather also makes it more comfortable for outdoor activities like hiking and visiting local markets.
For travelers who prefer slightly cooler temperatures and fewer crowds, the shoulder months of April and October can also be good options, though there's a higher chance of occasional rain showers.
